Boris Johnson's climate change spokeswoman has admitted she still drives a diesel car and does not "fancy" switching to an electric "quite yet".
Allegra Stratton told Times Radio she used her "third hand" gas guzzling VW Golf for 250-mile trips across the UK to see relatives.
When pressed on why she did not drive an eco-friendly electric vehicle, she claimed lengthy waits to charge the battery put her off.
It comes after the Government committed to banning the sale of petrol and diesel cars by 2030, with the UK bidding to BE a world-leader on climate change ahead of hosting the COP 26 summit in Glasgow later this year.
"I have a diesel Golf," said Ms Stratton. "It's third hand and I've had it for eight years.
"I don't drive it very much because I live in London, and it wouldn't be right.

"I cycle, I've hurt my leg at the moment, but usually we cycle or get on the bus or walk most places.
"The car we use to go to granny's and grandad's who are mostly 200, 250 miles away."
There are estimated to be more than 42,000 charge points across the UK in over 15,500 locations, but Ms Stratton said she was still not tempted to make the change.
"My son would really like me to buy an electric car," she said. "I think it is the idea that right now, if I had one, any of those journeys to my dad in South Scotland, my mum in Gloucestershire, my in-laws in the Lake District and my gran in North Wales, they're all journeys, that I think would be at least one quite long stop to charge.
"And my kids are seven and four and I don't fancy it just yet.
"That's not to say that very soon, that technology, the charging points, we're already seeing an increase in numbers, we're seeing the cost come down, and we are seeing the range go up. So the direction of travel is great, and is swift.
"So I am optimistic that at some point, like so many families around the country, I'll go for it."
Kerry McCarthy, Labour's Shadow Minister for Green Transport, said Ms Stratton's admission showed the Government was not doing enough to encourage people to buy electric cars.
She said: "Based on her many excuses, it seems that even the Government’s own climate spokesperson doesn’t think they are doing enough to make electric vehicles attractive to drivers.
"Unfortunately switching to an electric vehicle, which I did three years ago, is not an easy choice for everyone. That's because the Government has cut electric vehicle subsidies year on year and is way off track in creating the nationwide network of charging points we need.
"Labour would help improve access to electric vehicles for all by providing interest-free loans to consumers and investing in charging infrastructure where it's needed the most."
